Abstract

In this study, the nitrogen and carbon sources, light conditions and higher temperature was applied to batch cultures of Astragalus trojanus Stev. Callus obtained in semi-solid WPM medium supplemented with 1 mg/L 6-benzyladenine and 100 μg/L selenium were transferred to liquid medium with the same composition under dark conditions. In order to investigate the effects of medium composition and culture conditions on biomass, astragaloside IV and cycloastragenol accumulations, 505 mg/L KNO3, 16 g/L glucose, light conditions (1000 lux) and 28°C temperature were implemented to cell cultures. Biomass did not ascend, however, accumulation of astragaloside IV (AST IV) and cycloastragenol (CG) was affected. The highest AST IV (0.3018 μg/mg) and CG (13.160 μg/mg) concentrations were detected in light conditions and KNO3 added medium, respectively. Addition of KNO3 instead of NH4NO3 increased cycloastragenol accumulation, but astragaloside IV decreased. At 28°C, neither of the components can be detected.

Abstract

The insect Callosobruchus maculatus, is responsible for serious damages in the storage of grains of diverse cultures, among them, the one of the beans. Therefore the development of substances capable of being an alternative to minimize agricultural losses and thus contribute to food security of the population is a current necessity. Thus, the objective of this work was to perform the synthesis of ibuprofen derivatives and to evaluate their effect on mortality of common bean weevil. toxicity tests of the derivatives were carried out with the Callosobruchus maculatus weevil through direct contact for 48h.The synthesis of the derivatives presented good yields (65 to 95%) and it was possible to perceive that they have a bioactive effect against C. maculatus, with a mortality rate of up to 100% after 24 hours of applicationusing a concentration of 1 mg/mlof each derivative in separate experiments.With this it is possible to emphasize that the derivatives produced and evaluated can be promising as pest control agents.

Paper Index :: : 07.4721/xxxxxxx

Abstract

The aim of the study is to identify the employees perceptions in manufacturing and industrial companies on green environmental dimensions The respondents in this study are the employees' from various manufacturing companies in Johor Bahru city centre, Johor state of Malaysia. This study employed the survey method by using a questionnaire to the focused group that consists of 250 respondents at the managerial and operational level in manufacturing and industrial companies. The green environmental dimensions of that was determined in this study are sustainable transportation, sustainable procurement, eco-labeling and sustainable marketing.. Results showed that the highest total average score is 57 percent agreement on eco-labeling dimensions, followed by sustainable marketing dimension with 56 percent agreement. The results suggest that the manufacturing and industrial companies at Johor Bahru city centre, Johor state of Malaysia specifically did appropriate practices on green environmental dimensions to enhance the environmental sustainability and efficiency on their business operations.

 

KEY WORD: Sustainable transportation, sustainable procurement, eco –labeling, sustainable marketing.

Abstract

Driver fatigue is a major exogenous cause of fatal road accidents and has implications for Malaysian road safety. The major aspect that causes human errors is fatigue/drowsiness due to task-induced factors or attitude/behavior of the driver. Therefore, it is necessary to identify significant index to detect driver fatigue and associate that index with the level of alertness, for road safety and for use by regulatory bodies. This can be carried out by observing the physiological behavior through the Event-related potentials (ERPs) and electroencephalography (EEG) measures. ERP's are very small voltage potentials that examine the information processing and characterize the brain structures in response to specific events or stimuli. Studies have shown EEG changes that are time-locked to sensory, cognitive or motor events.............

 

KEY WORD: Driver fatigue, electroencephalography (EEG), event-related potential (ERP), multilayer neural network (MLNN), adaptive neuro-fuzzy (ANF).

Abstract

In this paper, we consider an extension of perturbations to semi-Markov control problems. We then study process perturbations in which the instants between transitions are random variables. The discounted semi-Markov control problem and the limiting average semi-Markov control problem are considered. We proceed to a perturbation on the law transition probabilities and the discounted factor. For this, we consider the particular case where the transition time of the original semi-Markov process is a random variable that follows an exponential law.

 

KEY WORD: Semi-Markov decision problem, discounted expected criterion, limiting average criterion, perturbation, discounted factor.
